I believe the Samsung Frame TV comes with the One Connect box. A single cable connects the One Connect to the TV and all peripherals attach to the One Connect. If I were installing the Samsung Frame, I think I'd just install an electrical outlet behind the TV, run a cable inside the wall from the One Connect to the TV*, put the One Connect somewhere I could conveniently attach peripherals to it, and attach the TV to a conventional wall bracket.

However, if I were going to use a TV with a soundbar, I'd skip the Samsung Frame because a soundbar below the TV would make it obvious that the Frame is a TV, not a picture.

Don't forget also that if the Frame were hung on the wall at picture-frame height, it would be the wrong height for TV viewing**, i.e, it would be too high.

*The One Connect can be 49 feet from the TV.

**Unless you're going to stand while watching.
